Simplify ripple background drawing, fix ripple alphas

Eliminates an extra saveLayer on the background in the common case of
a rectangle-bounded ripple.

Ripples and backgrounds are now drawn at 50% opacity of the ripple
color, which ensures that both the ripple and background are visible
and that the pressed state has a correct combined alpha.

Also fixes a bug where hardware (RT) animation was getting turned off
prematurely.
